about dynamips

Dear all,
If i want switch simulation in GNS 3.0 then what can i do for that? Acttually i am not able to desine and simulate setup with switch.
Please replay me. :P

Dynamips does not support switch emulation. You can simulate a switch but you will not be able to telnet into it or perform any kind of configuration. You should check here for more clarification and answers to your dynamips questions.

There is no switch because of the complexity emulating such a device

hmmm, i would think that a switch would be easier to emulate than a router. layer 3 is much more complex than layer 2.

The hardware used for switching can not be emulated.

As networker said, currently the hardware (ASICs) used to perform switching cannot be emulated (sorry for repeating), it's actually much easier to emulate a router, since the algorithms used are software based...

Yes it is pretty much the layer 1 and 2 stuff that is just about impossible to emulate. BUT, you could buy 3 good servers and 3 switches.

Then you could connect all the switches together, and then connect 1 of each of the three servers to one of each of the switches.

Then you can run multiple routers on each one of the servers, some folks run up to a dozen on each server.

Then bridge one of the routers to the physical nic on the server.


Presto you have one MASSIVE network for 1/20 the price of all the real gear.

Is this easy, no.

Can it be done yes.

Will it perform like real gear, NO way. It will work, and will be sufficient for a lot of testing/learning type stuff. But it will not give enterprise performance.
